I searched but did not see that this was discussed before. Looks like Carnival broke ground on a new cruise port in Grand Bahamas. Another article said Carnival purchased 369 aches which should give them plenty of room.

I remember hearing about this before COVID but nothing since. Good news! I expect it will replace Freeport. I really doubt anything will ever replace Nassau, especially once the new terminal there gets built.
